NITED STATES DANIEL A. TOMPKINS AND FREDERICK OLIVER, OF CHARLOTTE, N.C.

OlL-SEED-MEAL-HEATING MACHINERY.

S ECIFICA ION forming part of Letters Patent No. 336,175, dated February16,1886.

Application filed October 18, 1884.

To all whom it may concern:

Be it known that we, DANIEL A. Tonr- KINS and FREDERICK OLIVER, citizensof the United States, residing in Charlotte. county of Mecklenburg, andState of North Carolina, have invented a new and useful Machine forHeating Oil-Seed or Oil-Seed Products Preparatory to Pressing the Oilout of it, of which the following is a specification.

Our invention consists of one or a series of pipes or eonveyer-troughswithin which is a spiral conveyer, and about which, in the ease of thepipe or pipes, is an annular space for holding steam, and in the case ofthe trough there are hollow walls and bottoms, also for holding livesteam.

The object of the invention is to heat the meal uniformly, and to keepit stirred with little power to prevent burning. \Ve attain theseobjects by the mechanism illustrated in the accompanying drawings,-inwhich Figure l is an elevation of the entire machine, showing a sectionof the top conveyer and tubes. Fig. 2 is an end elevation, showing thehousing for holding the bearings of the spiral conveyers and the gearingby which all the other conveyers are driven from the one to which thepower is applied. Fig. 3 shows a sectional View of the shape in which aconveyer-trough may be made instead of tubular.

Similar letters refer to similar parts in the views.

To make the machine of pipes or tubes, as shown in Fig. 1, we wouldscrew the inner pipe into the castings A and K, having an outer pipewith steam-joints also at the castings. These joints on the outer pipemay be made with the casting by having long threads on each end of thepipe and having a sleeve and jam-nut screwed on the pipe before it isput over the inner pipe. Then, when the inner pipe is in place, screwthe sleeve so as to lap on the casting and the pipe, making asteam-tight joint on the casting, then jam the nut back of it on thepipe, having previously packed the joint. The arrangement of the twopipes is shown at section B B.

At V V the space for steam is indicated.

Serial No. 145,868. (No model.)

Steam is supplied to this space through the valveO from a pipeleadingfrom some steamsupply. The water of condensation is led away through thevalve P, and is either discharged or conveyed to the boiler through asteam-trap or by gravity, according to the height of the heater.

Q Q. &c., represent the spiral convcyers. L and M are pulleys fordriving these spiral conveyers, and U U U are geared wheels for drivingthose which do not receive power from the belt from the one which does.

0 is the housing for bearings,shown in ele- Vation, Fig. 2.

To operate the machine, oilseed oroil-seed product is put into it at Awhile the machine is being driven. It is conveyed through the length ofthe pipe by the movement of the spiral conveyer to the opening B, whereit falls into the conveyer-tube D, and is likewise conveyed through itto space 'or opening S, thence through the lower pipe, and out at T.Each of the pipes having an annular space of steam, the oil seed orproduct in passing through is gradually and uniformly warmed, and at thesame time is constantly kept stirred or in motion, which preventsburning or scorching from lying still against the sides of the hot pipe.

By the means of this machine we obtain a continuous feed and acontinuous discharge. The discharge may be directly into the former boxor into some receptacle.

The machine may consist of any number of conveyer-pipes orconveyer-tronghs.

A variation in the length of time required for the productto passthrough amaehine may be made by the use of cones or cone-pulley wherethe power is applied.

\Ve claim as our invention 1. In an apparatus for heating oilseed oroil-seed meal, a series of connected but independently-jacketedconveyers adapted to feed the material operated upon from one to anotherand alternately in opposite directions, and to discharge the samecontinuously, in combination with means, substantially as described,whereby any one or all of the jackets of said conveyers can be suppliedwith steam orits equivalent forheating said material, substantially asdescribed.

2. In an apparatus for heating oil-seed, the combination of theindependentlyjacketed screw-conveyers, geared together to he rotated inalternately opposite directions, and means for supplying steam to anyone or all of the jackets of said conveyers independently each of theothers, substantially as described.
